Calculate the answer. Express it in scientific notation and include the correct number of significant figures. (12 x 10^4 ) x (5 x 10^-2 ) =

Which type of intermolecular attractions holds ammonia molecules together with other ammonia molecules?

The appropriate concentration for an iodine sanitizer is

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
